The man charged in the shooting death of teenager Trayvon Martin in February must continue to wear a GPS monitoring ankle bracelet and remain in Seminole County, a Florida judge ruled Tuesday.

George Zimmerman is accused of second-degree murder in the Feb. 26 shooting of the 17-year-old in a gated Sanford community where he was on neighborhood watch. Zimmerman is claiming self defense.

Judge Debra Nelson also rejected a request to lower Zimmerman's $1 million bond, and ordered that Zimmerman remain in Seminole County and away from the Orlando-Sanford International Airport. In doing so, she kept in place a July ruling by Judge Kenneth Lester who previously presided over the case.

"He doesn't need to live under constraints that a previous court imposed," Zimmerman attorney Mark O'Mara said before the ruling. "This is not a person who has missed court appearances. He wants to be here. He's looking forward to an immunity hearing and a trial."

O'Mara also pulled out photos of Zimmerman's bloody face from the night of the shooting and asked Nelson to consider Zimmerman's innocence in making her ruling.

After hearing from both Assistant State Attorney Bernie de la Rionda and O'Mara, Nelson denied the motion saying Zimmerman would remain under the conditions set by a previous judge.

Nelson did agree to allow Zimmerman's lawyers to re-depose Sanford police investigator William Erwin, whom the defense says was present when police played 911 audio for Trayvon Martin's father. And the state also must turn over the original recording of Martin family attorney Benjamin Crump's interview of a girl identified as Trayvon's girlfriend, Nelson ruled.

Police say the teen's father initially denied that the voice heard screaming on the 911 call, before the fatal shot, was his son. The girlfriend, identified as Witness 8, says she was on the phone with Trayvon in the moments before the shooting. She is a key state witness.

On the GPS questions, Zimmerman argues that he "needs to be able to travel more freely... for reasons of his own personal safety and... to have the ability to assist his defense" by meeting with witnesses, including experts," according to a motion filed by his attorney.

Zimmerman will remain free on $1 million bond -- with the GPS monitoring -- while awaiting a trial scheduled for June 13.
